The neuropeptide BW receptor 1 (NPBW1, provisional nomenclature [2]) is activated by two 23-amino-acid peptides, neuropeptide W (neuropeptide W-23 (NPW, Q8N729)) and neuropeptide B (neuropeptide B-23 (NPB, Q8NG41)) [3,11]. C-terminally extended forms of the peptides (neuropeptide W-30 (NPW, Q8N729) and neuropeptide B-29 (NPB, Q8NG41)) also activate NPBW1 [1]. Unique to both forms of neuropeptide B is the N-terminal bromination of the first tryptophan residue, and it is from this post-translational modification that the nomenclature NPB is derived. These peptides were first identified from bovine hypothalamus and therefore are classed as neuropeptides. Endogenous variants of the peptides without the N-terminal bromination, des-Br-neuropeptide B-23 (NPB, Q8NG41) and des-Br-neuropeptide B-29 (NPB, Q8NG41), were not found to be major components of bovine hypothalamic tissue extracts. The NPBW2 receptor is activated by the short and C-terminal extended forms of neuropeptide W and neuropeptide B [1].
